This specification covers a titanium alloy in the form of forgings 3.000 inches (76.20 mm) and under in nominal diameter or least distance between parallel sides and 9 square inches (58 cm2) and under in cross-sectional area and forging stock of any size (See 8.5).

Rationale:
AMS4976J results from an update of this specification that revises the title, restricts material to the sizes of the mechanical property tables (1.1), requires vacuum in the first consumable electrode melt (3.2), requires agreement on mechanical property values for material outside size ranges (3.5.1.1.3 and 8.5), adds AS6279 (3.7) and revises the report paragraphs (4.4).
